IoV Terminal Multi-Carrier Data Transmission Parameter Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Internet of Vehicles (IoV) system lacks a method for performing data transmission, particularly in multi-carrier transmission modes, which affects the efficiency and reliability of data communication between Vehicle User Equipment (VUE) and Pedestrian User Equipment (PUE) terminals.
Innovation Solution
A data transmission method and terminal configuration that determine the data transmission mode of a carrier and obtain multi-carrier transmission parameters, such as transmission power, coding, modulation, and physical resource block limits, to perform data transmission using these parameters, especially in multi-carrier and data repetition modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-carrier transmission mode is used in IoV system, then spectral efficiency is improved, but transmission parameter configuration complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting transmission parameters (power, coding, modulation, resource blocks) based on carrier type and data transmission mode. The terminal determines whether to use multi-carrier or single-carrier mode and configures appropriate parameters for each scenario, resolving the contradiction between spectral efficiency and configuration complexity.
2Reliability
If data repetition mode is used across multiple carriers, then transmission reliability is improved, but resource consumption increases
Solution Approach 1:
The patent applies local quality by configuring data repetition selectively based on carrier type and service requirements. Not all carriers use repetition mode - the system determines which carriers need redundancy based on local conditions, thus improving reliability where needed while avoiding unnecessary resource consumption on carriers where it's not required.

AI summary
The disclosure provides a data transmission method and a terminal in an Internet of Vehicles (IoV) system. In the embodiment of the present disclosure, the terminal may implement the data transmission method in the IoV system by determining a data transmission mode of a first carrier, then obtaining the multi-carrier transmission parameter of the first carrier if the data transmission mode of the first carrier is a multi-carrier transmission mode, and transmitting data on the first carrier using the multi-carrier transmission parameter.
